My invention relates to building construction and particularly to apressure relieving and wall strengthening joint.

Among the objects of my invention is to provide a pressure relieving andwall strengthening joint having a unitary structure thereby eliminatingthe necessity of fillers; to create a joint formed of a single sheet ofmaterial, and having a plurality of integral raised portions adapted tobe forced down by excessive weight to relieve pressure; to supply ajoint adapted to be folded on itself to produce a water tight course,and such other objects, advantages and capabilities as will later morefully appear and which are inherently possessed by my invention.

While I have shown in the accompanying drawing preferred embodiments ofmy invention, yet I wish it understood that the same are susceptible ofmodification and change without departing from the spirit of myinvention.

Fig. 1 is a detail view of my compressible filler before it has beenbent on itself to form the upper and lower layers for the finishedproduct; Fig. 2 is a sectional view of my filler as it appears when afinished product; Fig. 3 is a sectional View of another embodiment of mywider type of joint where the raised portions on the upper and lowerlayers contact each other; Fig. 4 is a sectional view of Fig. 3; Fig. 5is an enlarged sectional View showing my folded joint in use in buildingconstruction; Fig. 6 is a similar view to Fig. 5 but of my wider type ofjoint.

One form of my compressible filler l3 shown in Fig. 1 comprises a bodymember l1, adapted to be bent back on itself preferably at 22 to form anupper portion or layer i8 and a lower portion or layer I9. A pluralityof raised portions 20 all preferably of substantially the same height onboth layers l8 and I9 are spaced to leave a plurality of unraised spaces2|. In the form shown in Fig. 1, the raised portions 20 on the upperlayer l8 are placed so that when the body member is bent on itself, saidraised portions 28 will contact unraised spaces 2! of the lower layerHi. In the form shown in Fig. 4, the raised portions 20 on the upperlayer l8 are placed so that when the body member is bent back on itself,said raised portions 20 on the upper layer will contact raised portions20 on the lower layer l9 and thus provide a wider type of joint.

It is also Within the contemplation of my invention that some of theraised portions 20 on the upper layer I8 are placed so as to contact insome instances raised portions 20 on the lower layer [9 and in someinstances will contact unraised spaces 2| on the lower layer [9.

While I prefer to construct my joint or filler l3 of ductile metal suchas lead, or fiber, rubber or the like, yet it is within the spirit of myinvention to construct my joint I3 of any compressible material havingsubstantially the same qualities and features as lead. My inventionproviding for a joint of one piece of material eliminates the necessityof expensive fillers. By eliminating the need of any filler and makingmy joint of one integral part, I substantially decrease the cost andamount of material and labor.

While I have shown as illustrated in the drawing, raised portions incircular form, yet I wish it understood that my raised portions may bein the shape of squares, triangles, rectangles, bumps or any other formof raised portions without departing from the spirit of my invention.The size, height and number of my raised portions are not materialexcept in so far as they affect the maximum results contemplated by myinvention.

My joint may be used in any type of building construction, andparticularly where the construction is divided into zones. My joint maybe placed in any place and as many times as desired within each zone,and at any place between units of a wall.

In use when my joint or filler I3 is inserted within the zone of any ofthe types of building construction my joint is load sustaining. Whenstresses and movements are thrust upon the fac ing blocks of thebuilding so as to create a superimposed load, my joint compresses by theraised portions thereof being forced down and consequently absorbsthe'thrust resulting in protection of the facing blocks from cracking orspalling. My joint is also a strengthening member functioning to preventloss of mortar due to breaking and substantially eliminating the needfor future tuckpointing.

My form of joint is particularly efiicient in that it is unitary instructure. When stress is applied to my joint the raised portions tendto break down in proportion to the weight thrust thereon and thus absorband compensate for added stress and weight. In building constructionwhere unusual weight and stress are-contemplated the form of my jointshown in Fig. 3 providing a Wider type of joint is more useful in thatit is adapted to absorb greater stress and weight.

My joint is particularly useful in wall structures made of glass whichare in many cases susceptible to cracking from expansion and othercauses. Frequently where the wall structure is glass I find it desirableto use more than one joint within a zone.

Having thus described my invention, I claim:

1. A unitary compressible filler for use as a pressure relieving jointin a wall structure comprising a sheet of metal bent upon itself to forman upper layer and a lower layer, said sheet having a plurality ofraised portions spaced so that when said sheet is bent back upon itselfthe raised portions of one layer will contact unraised portions of theother layer.

2. A unitary compressible filler for use as a pressure relieving jointin a wall structure comprising a sheet of metal bent upon itself to forman upper layer and a lower layer, said sheet having a plurality ofraised portions spaced so that when said sheet is bent back upon itselfthe raised portions of one layer will contact the raised portions of theother layer.

3. A compressible filler for use as a pressure relieving joint in a wallstructure comprising upper and lower metal members, said members havinga plurality of raised portions spaced so that when one of said membersis positioned above the other of said members, the raised portions ofone member will contact unraised portions of the other member.

4. A compressible filler for use as a pressure relieving joint in a wallstructure comprising upper and lower metal members, said members havinga plurality of raised portions spaced so that when one of said membersis positioned above the other of said members, the raised portion of onemember will contact raised portions of the other member.

5. A compressible filler for use as a pressure relieving joint in a wallstructure comprising a sheet of metal folded to form upper and lowerlayers, and interposed spacing means comprising integral raised portionson said layers.

6. A compressible filler for use as a pressure relieving joint in a Wallstructure comprising a single pair of oppositely disposed metal membershaving raised portions, said members adapted to withstand a desired deadweight without substantial compression but adapted to be compressed byexcessive pressure.
